It looks like a terrible idea cobbled together in a boardroom of people out of ideas trying to figure out what's popular with the youth these days. One can only imagine how it went down;
"Right people, we're out of ideas and we need a plan...we need something to sell, that ticks all the boxes on what's hot today. I want to leave this room with an attractive brief summary, an elevator pitch that shines with the words 'ALL the money.' Now hit me up with what you got!"
"Anime!"
"Ok. Good, nice try there, but you're forgetting that's what we do anyway. I meant other ideas we haven't thought of. Hit me up!"
"...Vampires!"
"Great! Yes! That's exactly the hack brainstorm material we need! Excellent work! Keep it coming."
"Dark Souls!!
"Brilliant! That is something I hear about everywhere, it must be popular! What else you got, people??"
"Uhhhh...ice cream!"
"Y...what?? Alright, I'll let that slide for now, maybe we can do something with it later. Gimme something else, something dramatic that all the kids love these days."
"Ehhh...hmmm, a...an...Apocalypse!!!"
"Fucking yes! Couldn't have asked for better myself...you're promoted, Stephens! This is profit-coated profit with profit flavoured filling; vampire dark souls apocalypse anime for all the kids to enjoy... let's make all the money, people...no time to waste! Don't bother with the story, we'll just make it up as we go along."
